/P> Known pontoon link, consisting of two outer and two medium pontoons 
The disadvantage pontoon link is great resistance and the flooding of the deck Shuttle ferry, in the fore part of which is installed pontoon link. This shortcoming is a consequence of the fact that the boat pontoon element is a vertical poorly streamlined wall.
The disadvantage of this river link as pontoon link Germany is considerable resistance and the flooding of the deck Shuttle ferry when using his bow river link. Currently, in the fore part of these ferries both domestic and foreign pontoon parks uses a special coastal link. However, a number of them in the kit of the Park is strictly limited, as for the floating bridge need only two coastal managers. The remaining coastal links at the bridge crossing is not used. In this regard, for example, in domestic montanadeleon ferry.The invention is directed to solving the problem of increasing the efficiency of the pontoon level by providing opportunities for its use in the bow of the Shuttle ferry maintaining the quality of river link.The solution of the stated problem is achieved by the fact that in pontoon chain comprising pivotally connected two outer and two medium pontoons fitted on the transom misbelieve butt nodes, one boat pontoons are made with clean lines, while average equipped with pontoons attached to them turning relative to the axis perpendicular to the longitudinal axes of the pontoons, and equal to the width of the fairing, made in the shape of a triangular prism, one side of which is in the lower position of the fairing, and the other facet it in the upper position are a continuation of the smooth contours of the middle pontoons, and the third side face provided with misbelieve butt nodes. In addition, at the pontoons by smooth contours provided with relatively rotatable attached to the walls of salesoutlook vertical axes reflecting shields.The invention allows to increase the number of Shuttle ferries, assembled from the kit of the Park, and at the same time to ensure wash">In Fig. 1 shows a pontoon link in the open (operating) position, plan, and Fig. 2 is a view along arrow a in Fig. 1; Fig. 3 cross-section B-B in Fig. 1; Fig. 4 is the same, with a raised fairing of Fig. 5 is a view along arrow b of Fig. 4; Fig. 6 the node I in Fig. 1; Fig. 7 is a view along arrow G in Fig. 6; Fig. 8 site II in Fig. 5; Fig. 9 is a view along arrow D in Fig. 8.Pontoon link consists of far pontoons 1, 2 and medium-sized pontoons 3, 4, interconnected by means of hinges 5, 6 and 7. In the open (operating) position the pontoons are connected, in addition, deck locks 8, made for example in the form of a collar brace and bottom locks 9 made, for example, in the form of eyelets with retractable pins. On one pontoon transom link average pontoons 3, 4 is equipped with misbelieve butt sites, made for example in the form of ear 10 and the plug 11 with a sliding pin. On the other transom link outer and middle pontoons are made with smooth contours and medium-sized pontoons 3, 4 fairings fitted 12, 13, secured to the pontoons rotatable with respect to the axes 14, 15, perpendicular to the longitudinal axis of the middle pontoons. Fairings are equal in length to the width of the middle of the pontoons. Each fairing is made in the form of a triangular prism, one side of which the lower is their pontoons. The third side fairing equipped misbelieve butt nodes in the form of ear 16 and the plug 17 with a sliding pin, similar in design meisenheim butt nodes 10, 11, placed on the opposite transom link. At the pontoons 1, 2 by smooth contours provided with reflecting panels 18, 19, relatively rotatable attached to the walls of salesoutlook vertical axes 20, 21. In the folded transport position of the link-reflecting shields posted along kresources and fixed by means of retractable pins 22 mounted in the sleeve 23. Identical in design to the pins 24 and sleeve 25 provided with fairings 12, 13. In the lower position, the fairing is fixed by means of swivel hooks 26, put on the buttons 27. When the fairing is raised to the upper position, the hooks 26 fixed in a spring clip 28.The proposed device operates as follows.Pontoon link unloaded vehicle on water and it expands. After that, close the deck locks 8 and bottom locks 9 and used pontoon link along with the river links pontoon parks to build floating bridges and ferries, connecting them to each other using misbelieve butt of nodes 10, 11, 16, 17 ostovic 29. If the pontoon link is supposed to be used as a nasal in the Shuttle ferry, snap hooks 26, releasing the buttons 27, translated using pontoon arm fairing up and fix their pins 24. Then choose to unpin it seawall panels 18, turn them 90aboutand fix the pin 22. Using the joint between bridge boats nodes 10, 11 pontoon link connect with extreme river link Shuttle ferry and begin crossing technique. Disassembly of the ferry and the folding pontoon link in the transport position is performed in reverse order. 1. The PONTOON ELEMENT comprising a hinge connected between two extreme pontoon with colocotroni and two middle pontoon posted on their transom misbelieve butt nodes, characterized in that on one side of the link of the boat pontoons are made with clean lines, while average pontoons equipped with a fairing, mounted with a possibility of rotation about axes perpendicular to the longitudinal axes of the pontoons, and is equal to the width of the middle of the pontoons, and the fairings have the shape of a triangular prism, one of the side faces of which in the lower position of the fairing, and the other in its upper position obrazuyemykh butt nodes.2. The link under item 1, characterized in that the smooth contours of extreme pontoons installed seawall panels can be rotated relatively attached to the walls of salesoutlook vertical axes.
